Answer: Plan A is cheaper, because the cost of a 2-minute call and a 4-minute call is less than the cost of a 2-minute call and a 4-minute of Plan B call.
Step-by-step explanation:
1. You have the following information of Plan A:
- A 2 minute call costs .54 cents.
- A 4 minutes call costs $1.08.
2. For Plan B, you know that the cost of
is given by the equation:
![y=0.289x](https://tex.z-dn.net/?f=y%3D0.289x)
3. Therefore, you can compare both plans by finding the cost of a call of 2 minutes and a call of 4 minutes of Plan B. You can calculate this by giving these values to
:
![x=2\\x=4](https://tex.z-dn.net/?f=x%3D2%5C%5Cx%3D4)
4. Substitute the values into the equation:
(This is more expensive)
(This is more expensive)
5. Therefore, Plan A is cheaper, because the cost of a 2-minute call and a 4-minute call is less than the cost of a 2-minute call and a 4-minute of Plan B call.
